Boiling water is poured into the sink to deal with oil pollution blockage.
Because the reason why the sink is blocked the most is that the fat sticks to the pipe and can't let the garbage out. So you should boil a pot of boiling water and pour it into the sink, and then add some cold water. If the water heater is connected to the kitchen, it will be better. If it is hot water, it will take 2-3 minutes. If it is winter, it can take longer. If you do this, you can clear the completely blocked sink. However, we must pay attention not to easily open the inverted water bend or dust cup, because the sealing rubber pad is damaged or the device is not good, it will leak water.
Water puller sucks loose sundries to deal with water tank blockage.
If the sink is blocked, it should be treated with a water plug, and of course, the lower mouth of the water plug must be sealed with water. Moreover, water can seal the air. So cover the drain and press down hard to empty the air and water in the drain, which will bring things out or loosen them. But generally, if there are many sundries, it needs to be pulled out several times.
Steel wire hooks out impurities to deal with water tank blockage.
If the straight sewer pipe is blocked, the front of the steel wire can be bent into a small hook, and then the impurities can be hooked out with the steel wire. Or put more than half a basin of water in the sink first, then lump a rag into a ball, and press the rag in the water with both hands at the lower outlet of the sink and press it up and down. Of course, it can also be treated with toilet plunger.
